Abstract PDF: OBJECTIVES
Previous studies showed that death certification by physicians was an important predictor to improve the quality of death certificate data in South Korea. This study was conducted to examine the proportion of death certificates issued by physicians and associated factors in South Korea from 1990 to 2002. METHODS: Data from 3, 110, 883 death certificates issued between 1990 and 2002, available to the public from the National Statistical Office of Korea, were used to calculate the proportion of death certificates issued by physicians and to examine associated factors with logistic regression analysis. RESULTS: The overall proportion of death certificates issued by physicians increased from 44.6% in 1990 to 77.6% in 2002 (mean: 63.5%). However, the proportion was greatly influenced by the deceased's age. In 2002, more than 90% of the deceased aged 51 or less were certified by physicians. A higher proportion was found among deceased who had tertiary education (college or higher) living in more developed urban areas. CONCLUSION: The information regarding the cause of death for younger, well-educated deceased in urban areas of South Korea may show a higher level of accuracy. Epidemiologic research using information on causes of death may well benefit from the continually increasing proportion of death certificates issued by physicians in the future in South Korea.; Summary

OBJECTIVES
To increase the booster vaccination rate, the Korean government legislated a measles vaccination for elementary school students in 2001, requiring parents to submit a certificate of vaccination upon the admission of the students to elementary school. The purpose of this study was to evaluate the validity of measles vaccination certificates which were issued to parents. METHODS: Using questionnaire survey data of 890 general practitioners and 9,235 parents in 2005, we investigated the evidence for booster vaccination certificates of measles. RESULTS: In the survey of general practitioners, 59.5% of the certificates depended on the medical records of clinic, 13.5% was immunization booklets, 23.7% was re-immunizations, 1.9% was confirmation of record of other clinics, and 1.4% was parents' statements or requests without evidence. In the survey of parents, 36.2% of the certificates depended on the medical records of clinic, 43.4% was immunization booklets, 18.0% was reimmunizations, and 2.4% was parents statements or requests without evidence. CONCLUSIONS: Our findings show that a majority of the booster vaccination certificates of measles was issued on the basis of documented vaccinations and it means that the implementation of the law requiring the submission of elementary school students' vaccination certificates has been very successful in Korea.

OBJECTIVES
Korea faces a number of challenges to meet demands in the area of geriatric professional medicine in a country with a rapidly ageing population. We evaluated the satisfaction and feasibility of the current education certification for geriatric physicians. METHODS: Geriatric physicians who were deemed qualified by the Korean Geriatrics Society during the period of 2001 to 2005 (n=2,200) were asked to complete structured questionnaires sent to them by mail about their satisfaction of and need for certificates of education, as well as their opinions on their geriatric specialty training. A total of 419 physicians responded. Descriptive analysis and hierarchical regression were performed to rate the respondents.satisfaction, the characteristics of the need for clarity and utility in education certification, and the characteristics of their patients. RESULTS: Although most respondents were satisfied with their education certification, those who had more elderly patients, aged 65 or older, and those who had more cognitively impaired patients, rated their education as significantly lower than did other physicians. Both groups expressed the need for more the comprehensive care and assessment concerning of their education. Multiple regression analysis indicated that satisfaction with geriatric physician qualification was associated with a physician's age, specialty, and percentage of elderly patients. CONCLSIONS: This study suggests that the current system of education certification is limited in terms of feasibility and physician satisfaction.

Abstract PDF: OBJECTIVES
This study was done to evaluate the reliability of education and occupational class between using the health survey and the death certificate data. METHODS: The 1998 National Health and Nutrition Examination Survey (NHANES) was conducted on a crosssectional probability sample of South Korean households, and it contained unique 13-digit personal identification numbers that were linked to the data on mortality from the Korean National Statistical Office. The data from 263 deaths were used to estimate the agreement rates and the Kappa indices of the education and occupational class between using the NHANES data and the death certificate data. RESULTS: The simple and weighted Kappa indices for education were 0.60 (95% CI=0.53-0.68) and 0.73 (95% CI=0.67-0.79) respectively, if the educational level was grouped into five categories: no-formal-education, elementary-school, middle-school, high-school and college or over. The overall agreement rate was 71.9% for these educational groups. The magnitude of reliability, as measured by the overall agreement rates and Kappa indices, tended to increase with a decrease in the educational class. The number of non-educated people with using the death certificate data was smaller than that with using the NHANES data. For the occupational class (manual workers, non-manual workers and others), the Kappa index was 0.40 (95% CI=0.30-0.51), which was relatively lower than that for the educational class. Compared with the NHANES, the number of non-manual workers for the deceased who were aged 30-64 tended to be increased (8 to 12) when using the death certificate data, whereas the number of manual workers tended to be decreased (59 to 41). CONCLUSIONS: The socioeconomic inequalities in the mortality rates that were based on the previous unlinked studies in South Korea were not due to a numerator/denominator bias. The mortality rates for the manual workers and the no-education groups might have been underestimated.; Summary
